JOSEPH KOENIG, OF TVO RIVERS, AND NICHOLAS DEDRICK, OF MANI- TOVOC,WISCONSIN, ASSIGNORS TO THE ALUMINUM MANUFACTUR- ING COMPANY, OF TWORIVERS, WISCONSIN.

COMB-TOOTH-BEVELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 648,759, dated May 1,1900.4

Application filed October 30, 1899. Serial No. 735,201. (No model.)

To all whom it may con/cern:

Be it known that We, JOSEPH KOENIG, a resident of Two Rivers, andNICHOLAS DED- RICK, a resident of Manitowoc, in the county of Manitowocand State of Wisconsin, citizens of the United States, have inventedcertain new and useful Improvements in Comb- 'looth-Beveling Machines;and we do hereby declare thatv the following is a full, clear, and exactdescription thereof.

Our invention has especial reference to the manufacture of aluminiumcombs; and its object is to provide simple economical self-feedlmachines for bevel-finishing of comb-teeth corners, said inventionconsisting in certain peculiarities of construction andcombination ofparts hereinafter particularly set forth, with reference to theaccompanying drawings, and subsequently claimed.

Figure l of the drawings represents a Vertical longitudinal section of amachine in accordance with our invention, this view being indicated byline l l in the succeeding figure; Fig. 2, a plan view, partly inhorizontal section; Fig. 3, a rear elevation of the machine; Figs. 4, 5,6,- and 7, detail parts of said machine; Fig. 8, a detail sectional Viewsimilar to part of the first figure, except as to position of thecomb-carrier therein; Fig. 9, a detail sectional View indicated by line9 9 inthe preceding ligure; Fig. 10, a perspective view illustratingpart of an escapement-movement embodied in said machine, the slip-dog inthis view being moved back against an opposing spring; and Fig. ll, aplan View of a finished comb.

Referring by letter to the drawings, A indicates the base of ourmachine, a portion of the same being higher than the remainder. On thehigher level of the base is a guideblock B for a carriage C, thatreciprocates in a direction longitudinally of said base, this carriagebeing provided with lateral studs b, engaged by boss ends of a yoke D,in union with a pitman E, by which it is connected to an eccentric F ona shaft G, that turns in standards H, rising from the lower level of theaforesaid base, said shaft being provided with a pulley I for adriving-belt.

In pivotal connection with ears c of carriage C -is a plate J, providedwith-a central slot in a direction longitudinally of the machine, andthis plate rests on a spiral spring CZ, seated in said carriage.plate-slot is a lug c, depending from a superimposed cross-plateK, theupper portion of this plate being a guide f for a carrier L, at rightangles to the one aforesaid, and a spiral Spring g is supported betweensaid lug and superimposedplate. A set-screw his arranged in a bracket ion a lug extension j of carriage C to bear against a similar extension7c of slotted plate J, and by adjustment of the screw the normal tilt ofthis spring-opposed pivotal plate and parts in connection therewith isregulated.

By means of screws m atemplet M is detachably connected to the undersides of lugs n,

tical inner grooves in the lugs is a spacingrack N, said lugs beingshown provided with two sets of thevertical grooves in order that theposition of the spacing-rack may be varied. Back of the spacing-rack thecarrier L is provided with a recess, in which a plate P is made fastflush with the top of said carrier, and extending up from this plate arestoplugs lo, that come in interstices between the teeth of a comb Q,supported on the aforesaid carrier. The comb is held snug against thestop-lugs p by slotted plates q, secured in adjusted position on Athetop of carrier L by setscrews r, engaging their slots, and in pivotalconnection with ears s, rising from said carrier, is a comb-clampcomprising angle-dogs t, connected by a rod u with an intermediatehand-lever o, that also constitutes part of the clamp,'said angle-dogsbeing opposed at their ends farthest from the comb by spiral springs w,seated on the aforesaid carrier.

By the means above specified a comb is accurately positioned on thecarrier L, the spacing-rack serving to correctly aline the combteeth,and a feed-,rack R in detachable connection with said carrier coperatesWithfast and slip dogs y, supported parallel to each other by aspring-controlled leverS, fulcrumed between its ends to the superimposedplate K, above specified, the lower end of this lever being inopposition to a lug z, ris- En gaglng the that extend from carrier L,and engaging ver- IOO ing from the machine-base. The slip-dog is inslot-and-pin connection with the fast dog on lever S, and a leaf-springy' is suspended from the upper portion of said lever to oppose one endof said slip-dog.

The mechanism set forth in the preceding paragraph constitutes anescapement for the comb-carrier L, and a flexible runner L', attached atits ends to said carrier, and a weight T is supported by a pulley T',suspended from an arm A' of the machine-base, the latter being provid edwith brackets U, that su pport stop-screws U' in opposition to saidcarrier, whereby the limit of movement on the part of this carrier ineither direction may be accurately determined.

A right-angle bracketV and a standard W on the machine-base serve asbearings for a spindle X, provided with adriving-pulley X', and a headY, provided with transverse peripheral blades, is made fast on one endof the spindle to constitute a cutter, the blades of which extendthrough a slot in a shield V', that constitutes part of said bracket, acover Y' for the cutter-head being detachably connected to the shield.An arm V" constitutes another part of bracket V, and alongitudinally-slotted plate Z is adjustably secured to the arm byset-screws Z in the path of -the templet M, above specified, u

As shown in Figs. l and 2, a comb is positioned on carrier L, and thelatter has had longitudinal movement a distance equal to one tooth ofthe feed-rack R, whereby an interstice between comb-teeth is brought inline with the cutter of the machine. By continued revolution of theeccentricF the carriage C and parts in connection therewith are moved inthe direction necessary to feed the comb to said cutter. By contact withshield V' the clamped comb is depressed and carried tangentially to thecutter just within the periphery of same for the length of out, thedepth of this cut being equal to the exposure of said cutter through theshield-slot, whereby, owing to proper shaping of the cutter-blades, asbest shown in Fig. 9, the otherwise rightangle corners of a pair ofcomb-teeth are accurately beveled. The length of cut in every instanceis determined by the templet M, and when the latter comes in abutmentagainst the stop-plate Z the superimposed guide-plate K and comb-carrierthereon will remain stationary, while plate .l and carriage C continueto travel incidental to a completion of throw on the part of eccentricFaforesaid, the spring g being compressed when this operation takesplace.

When the comb-carrying mechanism moves toward the cutter, thespring-controlled lever S has automatic movement to bring the fast dog:o into engagement with the feed-rack R and the slip-dog y clear of saidrack. At the same time there is contraction of the previously-expandedspring y to move the slipdog a distance equal to one tooth of thefeedrack. Now upon reverse movement of the comb carrying mechanism thelever S is caused to tilt on its fulcruin (against spring resistance) bycontact with lug z on the machine-base, whereby the fast dog is movedout of engagemen t'wit-h the feed-rack and the slip-dog /J brought intoengagement with the same, thus permitting partial descent of weight T tomove the comb-carrier a distance equal to one tooth of said feed-rack,the spacparture from our invention.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. Acomb-tooth-bevelingmachine comprising a cutter consisting of a headhaving transverse peripheral blades, a comb-carrier, feedregulatingmechanism in conjunction with the carrier, means for causing operationof the cutter on and between teeth of a comb upon said carrier, the combbeing tangential to said cutter just within the periphery thereof thewhole length of each cut, and templet and stop mechanism for regulatingthe length of cuts.
